Seasonal Flu (Influenza) Problem
Centers for Disease Control
The CDC website contains a wide range of information on the seasonal flu, spanning from demographic information and technical information about what 'is' the flu to practical information about preventative measures and treatments that would be of interest to patients. The information is comprehensive and detailed, and also includes special links to information for specific groups, such as the elderly and diabetics.
Objectivity:
Explain how content does or does not represent bias based on advertising or sponsorship.
Most of the data is scientifically validated and virtually all of the entries contain detailed references to matters such as the composition of the different flu viruses that are seldom found in other literature directed at the public. There are parts of the website designed to quiet reader fears in regards to who and who should not get different types of flu vaccines. All information reflects mainstream scientific views regarding the spread of the flu and how to prevent it.
Ease of Navigation:
Discuss the ease of use of this website for professional and for lay persons. Differentiate the ease of navigation for each of these 2 groups.
In addition to the general map of the website on the first page, there are multiple links within articles to areas of relevance for website surfers. Links are useful for both lay users and professional users. For example, in one article on vaccinating pregnant women, there is a useful link to recommendations for lay persons about who should get the vaccine but also a link to the Vaccine Safety Datalink (VSD) Project of the CDC's Immunization Safety Office, which might be of interest to professionals.

For professionals, the website is useful in explaining the differences between the different vaccines and for whom they are appropriate. For professionals, there is information about the precise composition of the vaccine virus and scientific discussion of the different types of vaccines and flus.
The immune system (led by the white blood cells, that communicate with other white blood cells that there is a fight ongoing) generates proteins that are called antibodies. They attach themselves to the virus and try to disable that pathogen. There are not enough white blood cells to rid the body of the influenza virus but there are enough antibodies to do the trick -- it just takes time,
Swine Flu You remember the great swine flu epidemic of 2009, right? Really, you don't remember the school's being closed across the country after the first wave of fatalities?

The risk to humans is generally low, however during any outbreak of Avian Flu among poultry, there is always a possible risk to humans who have contact with the infected birds and surfaces contaminated with excretions from the infected fowl (Avian1). The current outbreak of H5N1 among poultry in Asia and Europe is an example of a bird flu outbreak that has caused human infections and death (Avian1). In rare
